load-bearing channel bars, vibration isolators, by loosen-
ing 4 bolts.
The slot size should be about 2.5mm. The distance the
rotor is pulled onto the outlet nozzle should be 2.5mm.
The slot should always be checked following transport of
the device and its installation in the appropriate operating
position.

For fans with EC motors, the rotor slide on the hopper is
determined by the mounting bracket.
The ability of the rotor to rotate must be checked.

Continuous operation of the device with
the inspection panels off is prohibited.
Having made all the checks, the unit’s inspection panels
should be closed and the unit can be started up
7. Start-up of the Unit
Only qualified assembly personnel may carry
out start-up operations.
The recommended time setting on the inverters for start-
up/ warm-up of the fan is a minimum of 30s.
Start-up of the unit should be commenced with the adjust-
ment air damper shut at the inlet to the unit. Otherwise,
with the air damper wide open, the motor may be over-
loaded resulting in durable damage.
After the motor has been switched on, the adjustment
damper should be opened gradually, and the following pa-
rameters should be regularly monitored:
• the value of the intensity of the power consumed by the motor,
• the amount of air pumped in the installation (airflow rate).
If the unit is fitted with an control system, the opening of
the air damper by the servomotor should be controlled.
As a rule, the intensity of the power consumed by the mo-
tor should not be greater than the rated value, given the
assumed available amount of air and pressure.
When the fan is in operation, one should listen out for any
worrying, unnatural metallic noises or whether the unit’s
vibrations are not too heavy.
After 30 minutes the unit should be switched off and the
following fittings should be inspected:
• filters (if they have not been damaged),
• drip trays and traps (appropriate condensate drainage),
• fan section (temperature of motor and fan bearings – also the
slot between the nozzle and the fan rotor).
In units with secondary filters, start-up is recommend-
ed without this filters cartridge installed.
After start-up, it is recommended to clean preliminary
filters.
The antifreeze thermostat should be checked for correct
operation in temperature of air flowing into the water heat-
er of not much less than the thermostat setting – e.g. 1-2K.
Then, during operation of the unit the thermostat should
be checked for correct operation by shutting the inflow of
heating water for a moment.
Assessment of the correct operation of the EVO-T unit and
the air conditioning and ventilation installation (system
validation) may be issued after careful adjustment of the
operation parameters and after obtaining correct air pa-
rameters in the premises, assumed by the design.
The above-mentioned check operations should be done
before the EVO-T unit is commissioned.
When the EVO-T unit is started up for the
first time, the Assembly and Start-up Re-
port should be filled in (annex to the War-
ranty) or fill in the template according to
the p.13.
